  • You must own an Ethereum based NFT

  • NFTs must be ERC-721 or ERC-1155 on Ethereum Mainnet

How Does it Work

The inclusion of an NFT stamp serves two primary purposes: it signals your active participation in the Ethereum NFT marketplace and showcases the uniqueness of your collection. The Stamp is categorized into two segments:

  1. Collector's Journey: This aspect categorizes enthusiasts into levels based on their engagement and collection size on Ethereum Mainnet. The model based credentials recognize both ERC-721 NFTs and ERC-115 NFTs.

    • Digital Collector: For those new to the NFT space, starting to build their collection.

    • Art Aficionado: For collectors with a significant, well-curated portfolio that shows a deep engagement in digital art and assets.

    • NFT Visionary: Distinguishes users at the forefront of the NFT movement, showcasing exceptional collections that set trends within the community.

  2. NFT Ownership Verification

    • NFT Holder: Verifies users possessing at least one ERC-721 NFT on the Ethereum Mainnet, serving as the foundational credential within the NFT stamp category.

Checking Whether Your NFTs Meet the ERC-721 Standard

You can check your NFTs on Ethereum Mainnet on Explorer.

Go to https://etherscan.io/ and put your wallet address in the search bar.

On the overview section, select โ€œToken Holdingsโ€, and then โ€œView All Holdingsโ€

On the Token Holdings page, you will see the NFT Assets section where you can check all NFTs youโ€™re holding. You will also be able to see if you have any ERC-721 NFTs which will make you eligible for the NFT Holder credential.

Steps to Verify

After confirming that you have the required NFTs, follow these steps to claim the stamp

  1. Go to https://passport.gitcoin.co/ and "Sign in with Ethereum" to access your dashboard.

  2. Click Connect on the NFT stamp card.

  3. Click the Select all option then click Verify.

  4. Confirm your account is now verified. You can confirm this by seeing the button that previously read as โ€œConnectโ€ will now say Verified. Alternatively, you can inspect the Passport JSON.โ€‹


  • I have an NFT but Iโ€™m unable to claim the NFT Holder credential? Please verify that your NFT is an ERC-721 like in the image above. You can verify by going to etherscan, putting in your address and clicking on token holdings. If you have an ERC-721 NFT and you still cannot claim the stamp, please reach out to our Support team

  • I have an ENS. Why doesnโ€™t that count towards the NFT Holder stamp? You need to confirm that your Ethereum Name Service NFT is an ERC-721. The new Name Wrapped NFT is now an ERC-1155 and not ERC-721

  • Why did I successfully claim the NFT Holder stamp but the score was not added? If your NFT was transferred from another user who had previously claimed the NFT Holder Passport stamp with that same NFT, you might not see your Passport score updated even though you successfully verified the stamp. You will only get the score for it once the stamp has expired from the previous ownerโ€™s wallet after the 90 day expiration period.

  • What NFTs are allowed for the NFT stamp? The model based credentials (Collectorโ€™s Journey) recognize both ERC-721 or ERC-1155 NFTs while the credential for the "NFT Ownership Verification" only recognizes ERC-721.

  • I have many NFTs, why canโ€™t I claim the model based credentials? If your NFT stamp doesn't seem to reflect your activity accurately, or if you have questions about its assessment, we encourage you to initiate a conversation with us through this dedicated form. While we can't promise specific outcomes, we are committed to understanding your perspective and providing clarity on your stamp status. We value open dialogue and are here to ensure your engagements and collections are recognized appropriately.


If you encounter any issues during this process, our support team is ready to assist. You can reach out through the chat feature available at the bottom right corner of the Passport app.
